Millions of songs used in AI training datasets can now be searched by artist and title. The database includes large collections with roughly 12 million and 9 million tracks, plus two smaller sets with more than 100,000 songs each. Some of the material comes from public links to YouTube, Spotify, or music archives, but public access does not automatically mean permission for commercial training. The names reportedly found in the lists range from Lady Gaga and Radiohead to Aphex Twin, Wu-Tang Clan, Bruce Springsteen, and SZA, who said 238 of her songs appeared there.

The useful part of this case is that it makes a hidden supply chain visible. Musicians have been told for years that AI systems learn from vast amounts of culture, but that phrase keeps the damage abstract. A searchable database lets artists check whether their own work helped train a model, then ask who collected it, who downloaded it, and who benefits from the result. It also shows why consent becomes difficult once culture is treated as raw material at internet scale. A song can move from stream to dataset to model before its author knows it was part of the transaction.
